NAP-RESTORING DEVICE.

Application filed December 19, 1924-.. Serial No. 757,023.

This invention relates to improvements in devices for restoring nap tocloth, the de vice herein being particularly adapted for domestic use. pAn object is to provide a device in which perfect control of thecloth-engaging por* tions of the nap-producing or raising element can beobtained, and by which the working edge of this element can be broughttoward, into or away from the cloth in micrometric degree, enabling theoperator to produce nap of exactly the desired length or texture and,thus to accurately control the nap restoring operation.

Another object is to provide a nap restoring element, as a blade, whichcan be attached to an ordinary commercial type of safety razor handle orlike mount, in lieu and manner of a razor blade, so that the mount actsas a movable rest or support to be drawn along the goods during therenapping operation, and as a fulcrum about which the mount may berocked for bringing the working edge of the nap restoring r elementtoward, into or away from the goods.

Another object is to provide a mounting for the blade, which has arounded working edge, and in which the nap restoring element, whenattached to the plate, is slightly spaced away from the rounded workingfulcrum edge or bears a tangent relation to the edge, and is thereforespaced outwardly therefrom.

A more specific object of the invention is to provide a reversiblerazor-like blade which may be attached to a razor handle of a commercialtype, the blade having along each of two parallel sides a straight rowof nap raising or producing teeth each of different iineness, wherebyeither edge of the blade may be used and the blade substituted for theordinary razor blade to act as a cloth surface renishing tool,controlled and manipulated by the mounting and handle.

Another object is to provide a device for the above purpose which may becheaply manufactured either providing ak bladefor attachment'to a safetyrazor of the ordinary type, or as a combination blade and holderconstructed in accordance with the 1teachings of this invention.

Other objects and certain advantages will be disclosed in thedescription of the drawing forming part of this specification, in which:

Figure l is a side view of the device partly in section, shown inworking position, and illustrating the manner of att-ach-v ment of theblade to a safety razor handle of a commercial type.

Figure 2 is a face view of the blade.

Figure 3 is a cross section of the blade on line 3 3 of Figure 2.

Figure flis a vertical longitudinal section of the assembled device online 4-4 of Figure l.

The device comprises a curved plate 1, having a convex face 2, and alsoa concave face from which extends a handle 3. The plate is substantiallyrectangular, and its two longer parallel edges are provided withinwardly extending teeth or prongs 5. My improved blade is attached uponand against the convex face 2, is also rectangular, and is of slightlyless width than that of the convex face between the longitudinal`rounded fulcrum edges 4. The blade has two rows of knife edge teeth 8,A9, each of different lineness or spacing, and when the blade isattached, the tips of the teeth lie parallel with respective orcorresponding fulcrum edges d, with the teeth tangently related to therounded edges 4, and preferably spaced inwardly therefrom as shown inFigure l. The relative sizes of plate and blade are such that when theblade is attached flatly against the concave face, the rows of teethassume the tangent relation, thus causing the working points of theteeth to be slightly spaced away from the working edge. The teeth are,however, preferably beveled as at l() inthe manner of the edges of asafety razor blade, and the blade herein has generally the form of thattype of blade, except, for the toothed edges. The blade is secured uponthe plate preferably by a concavo-conveX retainer 11, which hascentrally of its concave side, a threaded stern 12 passing throughopenings 17, 18, in

lill) blade and plate and engaged with correspending threads oi' thehandle 3, so that when the parts are assembled, and the handle screwedto position, the retainer is drawn against the blade and said blade isiiexed and securely held. The extent of clamping actionxinay be 'varied'to flex the blade in the desired degree Vand therefore correspondinglyvary the degree of tangency relative to the conve'xjface or roundedfulcruin edge. The retainer also has two projecting pins 13, spacedequidistantly ateacli side of the stein 12, and these pins traversecorresponding openings '14, 15, in

plate. and blade.

Any 'convenientnieans of'fastening the blade may be used as Vwell asotherfornis of Yfulcruin plate anfd"han`dles for operating thesaine,`the important fea-ture beingthe relative disposition of thefulcruni Yedge of the lade, ywhereby adjustment of the plate v`plate andthe toothed edge or edges of the labout its fulcrurnedge or side variesthe Vextent of engagement between the teeth and cloth. y

The blade may be Aattached inany preferred manner sothatthe aboverelation l'between the fulcruin plate and the blade is obtained, and theplates maybe sold singly or in sets, either with 'or without holdersland inodifiedlin shapeto conform to other types of safety razor holdersor handles.

Having described iny invention, I claim: 1. In a device of the classdescribed, a

platehavinga straight edge, and a blade holder, said blade havingstraight rows 'of teeth on respective opposite parallel edges.

5. In a device ofthe class described, a plate having a straight edge,anda blade having a straight row of teeth along one of said edges, saidbladeattached to saidv plate with Vitsstrahght row of teeth adjacent thestraightI edge of the plate yand spaced outwardly frein the face' of theplate.

6. In a device of the class described, aV

plate having va straight rounded edger anda y blade havinga straightrow'of teeth along fone edge, 'said blade attached vto said `platewiththe row r'of teeth"overlying the 'curved `edge of they plate tangentthereto.

7. In a device of the class described, a plate having a straight roundededge and a blade having two parallel straight edges and teeth along saidedges with one row of teeth overlying the rounded edge of the platetangent thereto.

8. A plate having a straight edge and a blade having a straight row ofteeth, said blade attached to said plate with a row of teeth adjacent`and parallel with said straight edge and spaced outwardly therefrom.

9. In a device of the class described, a plate having a straight roundededge, and a blade having a straight row of beveled teeth, saidplateflatly attached to said plate plate and spaced inwardlyfrom the edgevand outwardly from the convex surface,

whereby when the plate is i'ocledl about its straight edge as a fulcruinthe teeth are adjusted to fard or away from the fabric.

11. In a device for restoringthe nap of fabric, a curved plate ofsubstantially rectangular configuration providing opposite parallelrounded edgesas fu'lcrunisfor roelc ing'the plate when one of the edgesis engaged with the fabric, a blade attachedto the convex side of theplate,`said blade having straight rows of teeth parallel with,`overlying and tangent to the rounded edges of the plate.

12. A flexible blade of substantially the dimensions of a safety razorblade, including spaced openings for attaching the blade,

said blade having straight rows of beveled teeth in lieu of razor edges,whereby the blade can be attached to the razor mounting or holder andmanipulated for a nap restoring operation by placing Aone straight edgeof the mounting against the goods as a fulcruni and rocking the devicein varying degree to vary the engagement of the teeth with the goods. Y

13. In a device of the class described, a plate 'having a'straightworking edge adapted to rest upon the goods and to actas a fulciuni, ablade' attached flatly against the plate, said blade having a straightrowy of i-loeveled teeth at one edge andspaced inwardly from said edgeand outwardly from the face of the plate, whereby when rocking the plate'about the working edge the 'degree of engagement of the teeth with thegoods` can be varied and controlled While drawing the plate across thegoods.

14:. In a device of the class described, a plate having a straight edgerounded 5 throughout its length, a blade attached to one face of saidplate having a straight row of teeth along one edge, the tips of theteeth lying tangent to the rounded portion of tho straight edge, andspaced outwardly from the rounded surface, and means for rocking theplate about its yrounded straight edge as a fulcruin to adjust the teethtoward, into or away from a fabric.

In Witness whereof, I hereunto subscribe my name.
